$50$ $50$ moons can fit inside Earth.

Volume of Earth is $1.09 \times 10^{12}$ $1.09xx10^12$ cubic kilometers

Volume of Moon is $2.18 \times 10^{10}$ $2.18xx10^10$ cubic kilometers

Hence number of Moons that can fit in Earth is

$\frac{1.09 \times 10^{12}}{2.18 \times 10^{10}}$ $(1.09xx10^12)/(2.18xx10^10$

= $\frac{10^{12 - 10}}{2}$ $10^(12-10)/2$ $" "$ as $2.18 = 1.09 \times 2$ $" "2.18=1.09xx2$

= $\frac{10^{2}}{2}$ $10^2/2$

= $\frac{100}{2} = 50$ $100/2=50$

The volume of the Moon is about 2.18×10102.18 xx 10^10 cubic kilometers. The volume of Earth is about 1.09×10121.09 xx 10^12 cubic kilometers. About how many Moons can fit inside Earth?
